Will not print... not a paper jam. - HP OfficeJet Pro k550 Printer

Is that true for both print and copy job ?
Where does the jam happen ?

I am thinking if it is at the paper pickup roller area just as the job starts to print and not midway while printing, check the paper quality; dirty pickup roller; clean cork pad and try job from another tray

Fix laser/Scanner
